McBride, Minvmleapolis,v Minn.v Application August 19, 1949,- serial No. 111,250 '1 1 Claim. (o1. 10s-5s) 'ThisV invention relates ture. .While this invention might have various v applications; it is particularly4 adapted for use in homes or small places of business or in business `roffices. It is desirable to have asafety box in such places for the safe 'keeping of jewels,V money or valuable papers. It is desirable to have 'such a safety box for. protection from loss by fire or theft. vSuch a safety box could be placed in a small space where it would not be noticeable and where it'could be fastened so that it would not be readily removable.

Itis an object of this invention to provide a relatively small safety box which will give protection against loss by fire or by theft.

It is another object of this invention to pro- Y videV a safety box comprising a locking means fastened to a floory or base, means on said box cooperating with said locking means and movto a safety box struc;

able longitudinally therein, means provided for.

kholding said box in fixed relationship to said -locking means for preventing longitudinal movementv of said Vbox Vto disengage said locking `means.

' It is a Yfurther object of this invention to prof vide a safety box structure comprising a casing generally rectangular in transverse section, said casing having a chamber therein, said chamber being fitted with a unitary box-likev member of insulating material, said casing and member being opened at one end, saidv casing being fitted with a door fitting in and closing one end.

vThese and other objects and advantages of .the invention will be fully set forth in the following description made in connection with the accompanying drawings in 'which like reference lte-rial,A preferably metalsuch as steel. yThe side Walls Hic are extended'downwa'rdlyfa short distance below thebottom wallflb and are bent -substantially at right angles to form plate-like portions lf'exteridingv toward each other. Casingill has a narrow front wall Iilg'at its lower portion which extends down tc the plane of the 'Y lower surface of'portio'n IIJf. Wall Ig 'also extendsvertcally at one side of casingl I0 at the frontend thereof, as shown in Fig. 1. Said front wall my is secured to said casing I0, as by weld- 4 ing, after member IB, presently to be described,

l is disposed .in said casing.

Y stanstantially equal to that of casing l0. Members i l have their channels facing outwardlyancl are rigidly connected to transversely extending bars l2 disposed adjacent their ends.v Bars I2 arereach provided With a plurality of holes l2a Y in which are disposed securing or foundation characters refer to similar parts throughout the 2 several views and in Which- Fig. 1 is a perspective view of the device of this l l invention;

Fig. 6 is a View in front elevation of aunitary lining member.

lis a unitary member vI6 having a Wall of considerable thickness which has therein a chamber 16a with parallel side walls and Which is substantially rectangular in cross section. Member I6 is made of a fireproof or fire resistant substance, such as a composition of sili-ca. Member [6 is open at its front end, the same having an offset portion l 6b with an outwardly ared inner 1surface IEC. Member I6 also has extending about recess ld rectangular in longitudinal section. Member I6 also has grooves |69' rectangular in cross section extending across its front end. Said grooves extendA centrally of 'each of three sides Referring to the drawings,- a device is shown comprising a'casing I0. While this casing might take various forms, in the embodiment of the invention illustrated, it is shown as substantially rectangular in vertical and horizontal cross sec- 4tion and of somewhat elongated form; Casing A `I 0 has a top wall I Ua, a bottom wall 10b, side walls L"^Ill"c,` a'rearA end Wall I0d and an open'fr'ont end |0e. Said casing will be made of plate-like maand at'right angles to said sides, 'as shown in Fig. 6. The fourth side |611, has a downwardly y'andi inwardly inclined upper edge portion. A

lining Il, preferablyA made of metal, is fitted in chamber 16a, the same extending along the bot- Y tom' of said chamber and a short distance upwardly along the sides of said chamber and being 'front-of casing i0 at the inner side thereof, said frameextending about the top, bottom, and one vertical side, this being the side shown at the 3 left of Fig. 4. Frame I8 is secured to casing I0 in any suitable manner, as by welding. Member I8 prevents the forward movement of insulating member I6. A hole Inh is formed through the bottom wall Illb adjacent its front end substantially midway between side walls Illc. n'

A door 20 is provided for closing the open end Ille of casing l0. Said door comprises an'outer hat plate member 20a. Said outer plate member is made of sheet material preferablyrof the same substance as the said casing. Y Mounted on the inner side of said plate member 20a is an insulating block 20h. Said insulating block is, made preferably of the same substance as the 'inner Aunitary insulating member. Secured to plate 20a inner orhinge end of said door plate whereby it swings under and is disposed under vertical front wall Ig when said door is closed and in closed position respectively. Extending through said outer plate 20a are bolts 20d passing respectively through anchoring plates 20e, the same being provided with nuts 20j. The inner portion of said bolts, as well as said anchoring plates and nuts are embedded in lsaid insulating block 20h, which latter is thus securely held in position. The sides of said insulating block 20 incline inwardly slightly to fit into and tightly close the open end I5c of the inner unitary insulating member. Said door is provided with a lock 2l.

' Said lock is positioned at the open end of said U-shaped plate 20c and is provided with a combination dial and handle 2Ia and with a bolt 2lb. When in closed position, said bolt extends through groove I6g and under frame I8, thus holding said door member in closed position.

A box or drawer 22 is provided and is slidably tted into lining I1. Said box is open at its top and is preferably made of metal and is provided with a handle 22a at its front side. Said box is adapted to receive various items or articles of value to be placed `within said casing for safe keeping.

In operation, members I2 are bolted to a base I4, such as a wooden or concrete floor, asshown in Figs. 2 and 3. Members Il rigidly-fixed to members I2 are adapted to receive portionsv Illf of casing I0, said casing thereby being longitudinally slidable on said members I I. When moved the full length of members Il, so that casing Ill is vertically over members I I and thus in normal position, a headed bolt or pin I5 is placed through opening Ih and is received in opening |25 thus preventing any longitudinal movement of said casing I0. Casing I0 of course cannot be lifted vertically due to portions If in members I I.

Money or valuables are placed in box or drawer 22, said box being disposed as described inside the unitary insulating chamber I6. The door or cover 2D is then placed in closed position. Member 20h lits into the open end |60 of the unitary insulating member land the outer plate member closes tightly the open end I0e of the casing I0. The unitary insulating member I6 and the block 20h fitting therein form a complete insulating wall about box or drawer 22 so that the same is perfectly insulated. The contents of box 22 would thus not be damaged in case of fire. The walls of member I6 as vstated are continuous and great safety is thus provided against lire.

From the above description it will be seen that I have provided a compact and conveniently handled safety box whichcan easily be placed in an obscurefor inconspicuous place. It is readily fastened to a floor member and the bolts holding the safety box in secure position are not accessible to anyone tampering with same. The device can conveniently be placed in a closet in a residence.

` contents of box'22.

The inner chamber is entirely enclosed with fireproof or re resistant substance. This', as stated, adds greatly to the safety of the This safety box is made up of relatively simple parts and can be produced Ato sell at a price that will extend out to a fiar lreaching market. This device has been amply tested in actual practice and found to be very successful and eflicient. It has been 'subjected to high temperatures for considerable periods without damage to the contents of box 22. The device is being commercially madev and is a great boon to farmers, city residents and oice proprietors.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and deiined in the appended claim.
